PHOTOS: Occupy protest at the Port of Seattle

Occupy Seattle protesters gathered Monday night at the Port of Seattle in an attempt to shut down the commerce hub.

Eleven were arrested after skirmishes with Seattle Police officers. At one point a protester threw a lit road flare and another threw what appeared to be red paint on officers.

During the brief melee police used pepper spray and flash-bang grenades that seemed to emit eye-stinging fumes to disperse the crowds. A trio of officers on horseback also helped clear the roadway during the protest.
